As part of the Evolution Wireless Digital family, the EW-DX series takes the complexities out of wireless and has been carefully engineered to not generate any significant intermodulation products.
Sennheiser has announced that the first EW-DX devices are shipping in North America, EMEA, Japan, and Singapore. Available products include the EW-DX EM 2 two-channel receiver, the handheld transmitter – with or without a programmable mute switch – and the bodypack transmitter. The latter also comes in two versions, either with a special 3-pin mic connector or a 3.5 mm (1/8”) jack for mics or instrument cables. Convenient set packages are available, too, with further, higher frequency variants ready in Q1 2023, and more EW-DX devices and software being added to the line in mid-2023.
Benny Franke, product manager at Sennheiser, said: “This awesome system combines pro features and ease of use in well-designed, rugged housings. We’re happy to see it hitting the market. EW-DX is a more than worthy technological successor to the evolution wireless G4 series and will be setting a new standard in the live audio industry for simplicity, reliability, audio quality and frequency efficiency.”
Like its EW-D sister models, EW-DX offers the lowest latency on the market (1.9 milliseconds), eliminates the need for frequency calculation, and offers an ultra-wide input dynamic range of 134 dB, enabling your transmitters to handle any signal that is thrown at them. Their operating time is 12 hours with the BA 70 rechargeable battery, which will usually take you through rehearsals and the show or event itself. Operating time with standard AA batteries amounts to eight hours. Depending on the RF environment, the transmitters have a range of up to around 100 m, enough even for very generous stage layouts.
EW-DX systems additionally benefit from an automatic multi-channel RF set-up, scalable remote control and monitoring, as well as AES-256 encryption for the secure transmission of contents. The bandwidth is higher than with EW-D, up to 88 MHz, enabling more channels to be accommodated.
The systems do not generate any significant intermodulation products. From a spectrum efficiency point of view, this means that the microphones do not pollute the available spectrum with their own intermodulation products, hence more transmission frequencies can be used and distributed evenly at regular distances (the so-called equidistant frequency grid or tuning grid).
In standard mode – i.e. with an equidistant frequency spacing of 600 kHz – EW-DX accommodates up to 146 links within its switching bandwidth, and up to 293 frequencies in Link Density Mode (LD, at 300 kHz spacing).
Franke commented: “The Link Density Mode will give you even more room to manoeuvre in a densely populated RF spectrum. The slight reduction in range is barely noticed during productions. EW-DX will give you peace of mind, knowing that audio quality and transmission power will not suffer. Signals will sound great, and will be reliably transmitted.”
EW-DX offers a choice of two bodypack transmitters – the EW-DX SK with a 3.5 mm jack for microphones and instrument cables, or the EW-DX SK 3-PIN for microphones with a special three-pin connector. The bodypacks can be used with any digital-proof Sennheiser clip-on and headset mic, the Neumann MCM system and digital-proof third-party microphones. The handheld microphone is also available in two versions: with a noiseless, programmable mute switch (EW-DX SKM-S) and without a switch (EW-DX SKM).
The EW-DX transmitters are the first on the market to feature e-ink displays – even when switched off, you will still be able to read off essential transmitter data. They are also fitted with an adjustable low-cut to reduce handling noise, or pop noise in a broadcasting situation. Settings are ‘off’, 30 Hz, 60 Hz, 80 Hz, 100 Hz and 120 Hz. All transmitters feature charging contacts for in-device charging of the BA 70 battery and an in-built test tone generator.
The EW-DX EM 2 is the first two-channel receiver to launch in the series.
The EW-DX EM 2 is fitted with an Auto Scan function, which will ably assist you in finding good frequencies for your receiver or multiple networked receivers.
The receiver is fitted with a headphone output with volume control, both balanced XLR and unbalanced 6.3 mm analogue outputs, and an RJ 45 port for Power over Ethernet and integration into control and monitoring networks. An OLED display shows both channels at a glance, and a link quality indicator helps avoid surprises.
This charger is also available in the EW-D charging set, complete with NT 5-20 UCW power supply unit and two BA 70 batteries. Meanwhile, the EW-D power distribution cable and matching NT 12-35 CS power supply unit will power up to four EW-DX EM 2 receivers and keep your set-up cleaner. The EW-D ASA active antenna splitter, EW-D AB antenna booster and ADP UHF passive, directional antenna complete the system accessories that are available now.
Following the launch of additional frequency variants and a network-enabled, two-bay, in-device desktop charger in Q1 2023, mid-2023 will see further hardware becoming available, such as two- and four-channel Dante receivers and a dedicated charging module for the L 6000 rack-mount charging unit.
